Description
Nutrient cardboard discs are dehydrated culture media discs intended for colony count determination using the membrane filtration method. Supplied as dry nutrient media in petri dishes, they provide a practical alternative to conventional agar media for microbiological quality control. A key advantage of this format is the long usability period of 24 months, supporting convenient laboratory stock management without frequent media preparation. The discs are designed for membrane-filtration workflows in which colonies are recovered and enumerated on the nutrient surface after filtration. Each pack contains 100 pc(s), with a net weight of 1,280 kg and a matching gross weight of 1,280 kg. Available from manufacturer Sartorius, these nutrient cardboard discs help standardise colony count testing while reducing day-to-day media handling compared with poured agar plates. The dehydrated presentation is suited to routine microbiology reagent use where reproducible colony enumeration and efficient membrane-based analysis are required. Laboratories seeking a ready dry-media option for membrane filtration colony counts can integrate these discs into established QC procedures with minimal preparation overhead.

Questions about Tergitol TTC NPS & gridded MF, 0.45m
What is this article?
Tergitol TTC NPS & gridded MF, 0.45m is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Ready-to-use culture media (plates, tubes, bottles), inside Culture media & microbiology, in Microbiology lab supplies.
A ready-to-use plate, tube or bottle is the medium already prepared and sterile. It saves the autoclave and it expires. The fill volume, the supplements and the storage temperature are the specification. A plate that has dried out or grown a colony of its own is finished.
A culture medium is the food and the solid or liquid home of a microorganism. Dehydrated media are powders the laboratory dissolves and sterilises. Ready-to-use plates and tubes are already that. A Petri dish is the plate. Selective media let one kind of organism grow and hold another back. The formulation and the supplements, not the colour of the agar, are the specification. Reference strains are at ATCC. Methods are on PubMed. Biosafety practice is the WHO laboratory biosafety topic.
